How to Make Easy Crock Pot French Onion Meatballs
- In a large skillet, melt butter with olive oil over medium heat. Add the sliced onions and cook, stirring occasionally, until deep golden and caramelized, about 25 minutes. Stir in flour and cook for 1 minute more to create the base for your sauce.
- Slowly whisk in beef broth and add thyme. Simmer for 3-5 minutes until slightly thickened, then remove from heat.
- In a large bowl, soak breadcrumbs in milk for 5 minutes. Add ground beef, egg, garlic powder, Worcestershire sauce, salt, and pepper. Mix gently until combined but not overworked.
- Form the meat mixture into 1 ½-inch meatballs and place them in the crock pot. Pour the caramelized onion sauce over the meatballs, ensuring they’re mostly covered.
- Cover and cook on low for 4 hours, or until meatballs are cooked through and tender.
- Thirty minutes before serving, sprinkle shredded Swiss cheese evenly over the meatballs. Cover and let the cheese melt.
- Garnish with chopped fresh parsley and serve hot with your favorite sides.
Tips for the Best Results
- Use a mix of ground beef with some fat for juicy meatballs; lean meat can dry out.
- Caramelize onions slowly over medium-low heat for maximum sweetness and depth.
- Don’t skip soaking breadcrumbs in milk; it keeps meatballs tender.
- If you prefer, substitute beef broth with a mix of beef and French onion soup for bolder flavor.
- Use a cookie scoop to shape evenly sized meatballs for uniform cooking.
Storage and Reheating
Store leftover french onion meatballs in an airtight container in the refrigerator for up to 3 days. Reheat gently in the microwave or in a covered skillet over low heat to preserve moisture.
For longer storage, freeze cooked meatballs and sauce in a freezer-safe container. Thaw overnight in the fridge and reheat slowly on the stove or in the crock pot before serving.
Frequently Asked Questions
Can I use ground turkey or chicken instead of beef?
Yes, you can substitute ground turkey or chicken, but be aware these leaner meats may result in a less juicy meatball. Consider adding a bit of olive oil or an extra egg to keep them moist.
Is it necessary to caramelize the onions first?
Caramelizing onions develops the rich, sweet flavor crucial to the french onion profile. While you can skip it, the overall taste and depth of the sauce won’t be the same.
Can I make this recipe in advance?
Absolutely! Prepare the meatballs and sauce up to the point of slow cooking, then refrigerate overnight. When ready, cook them in the crock pot as directed for a fresh, warm meal.
What are the best side dishes to serve with french onion meatballs?
Mashed potatoes, buttered egg noodles, or crusty bread all pair wonderfully with these rich meatballs, helping soak up the delicious onion gravy.
